The aim of this study was to evaluate the post-thawed characteristics of leopard cat semen. In this experiment, semen was collected from two leopard cats (A and B) at wild animal center in Seoul Grand Park in Korea. After collection, the sperms were washed with D-PBS and diluted by the freezing medium (Irvine science, USA) and stored in liquid nitrogen. The post-thawed concentration was $357{\times}10^6sperms/ml$ for A and $97{\times}10^6sperms/ml$ for B. The viability of post-thawed sperm from A and B individual was 24.0% and 19.0%, respectively. Pre-freezing motility of A and B individual semen was 68.54% and 56.65. Leopard cat A had more normal sperm than that of B (69.5% vs. 54.5%). Acrosome integrity analysis detected live (14.5% vs. 9.0%), damage (39.0% vs. 44.0%) and dead (46.0% vs. 47.0%) in leopard cat A and B, respectively. The present results concluded that leopard cat semen can be collected successfully by electro-ejaculation method and cryopreserved successfullyfor future use in different assisted reproductive technologies. The cryopreservation protocol needs to be modified for increasing post-thawed viability of leopard cat spermatozoa.

Zoological parks are considered to be a recreational place for family outings and most importantly the starting place of contact with animals in the modem society. Due to environmental threats and the loss of wildlife habitats, the zoos have significant roles to play in education, research and conservation in addition to the traditional role-entertainment, but research on zoos and their visitors is very limited in Korea. The present study surveyed that the zoo visitors' perceptions of the role of zoos, satisfaction, and behaviors in 6 public zoos, during which 730 zoo visitors were interviewed. The results indicated that the zoos represent an opportunity for family-based trips, enjoyment with family or friends and education that are the primary motives for visiting the zoos. The findings demonstrate that respondents considered the four main roles of zoos namely conservation, education, entertainment, and research to be important and recognize its value for conservation and environmental education. The determinants of satisfaction of zoo visitors were ease of visibility, welfare of captive animals, and the availability of information. Most respondents believed that naturalistic exhibits and animal welfare were very important. In order to reinforce the roles of the zoo in modem society, multidisciplinary efforts are needed to improve the animal welfare, replicate native habitats, and develop various education programs.

Aspegillosis in free-living birds can be occurred mostly under poor weather and climate. But, captive birds tend to be more susceptible to infection and diagnosis was made usually at post mortem. A two months old Whooper swan(Cygnus c. cygmus) dying suddenly was found in a zoo without prior clinical signs. At necropsy, numerous well- demarcated yellow to white firm nodules were scattered throughout the air sacs and the lungs. Microscopically, granuloma formations were observed in the lung and air sacs. The margin of granuloma was surrounded by connective tissue barrier and was infiltrated with lymphocytes, and also observed giant cell near the granuloma. By Periodic acid Schiff reaction, hyphae were detected in granuloma of lung and air sacs. This case was diagnosed as an invasive pulmonary aspergillosis caused by Aspergillus fumigatus infection in a Whooper swan at a zoo.

The present study was conducted to investigate biochemical characteristics and antimicrobial susceptibility of Aeromonas hydrophilia isolated from Jackass penguins (Spheniscus demersus) of zoo and capelins (Mallotus villosus). Seven of Jackass penguins showed anorexia, depression with seriously greenish vomiting for a few days, but resulted in 4 deaths although extensive treatment was carried out by zoo veterinarians. From the 18 samples composed of organs or feces from dead or live Jackass penguins and capelins, 4 (22.2%) Aeromonas hydrophilia were isolated and Bacillus spp, Staphylococcus aureus, Staphylococcus auricularis, Staphylococcus cohnii and Enterobacter aminigenus were also identified. Antimicrobial susceptibility tests of Aeromonas hydrophilia showed that all isolates were susceptible to amikacin, gentamicin, kanamycin, norfloxacin and trimethoprim- sulfadimethoxazole. However, all isolates were resistant to the following antimicrobials; ampicillin, bacitracin, c ephalothin, cefazolin, noboviocin, penicillin and vancomycin.

Three cases of hepatic encephalopathy were diagnosed in scimitar-horned oryxs housed at a zoo. Administration of amino acid and ornithine-aspartate fluid therapy via an intravenous injection decreased serum levels of ammonia and liver enzymes in cases 1 and 2. Further, additional oral ingestion of non-absorbable disaccharide lactulose to eliminate intestinal nitrogenous products enabled recovery of two oryxs. However, in case 3, the serum levels of ammonia and liver enzymes increased even after treatment, and the oryx died. Necropsy revealed cecum and colon compaction due to stiff dried feces, and this condition could have an adverse effect on increased blood ammonia levels that may have caused mortality. Overconsumption of pellets may have been the primary cause of hepatic encephalopathy. Thus, a fiber rich diet with decreased amount of pellets is needed to prevent hepatic encephalopathy, since the normal diet of scimitar-horned oryxs is rich in fiber.

This research was carried out in order to establish the production technique for Poong-san dog’s frozen semen, by examining the semen characteristic and the volume of glycerol added to the dilution solution, thawing temperature and sperm motility and viability as well as the motility using CASA according to time variation. Average semen volume was 5.9ml, sperm concentration 116.3×106 sperm/ml, total sperm number 789.3×106 sperm, motility 88.7±1.7% and viability 87.6±7.8%. When it was cryopreservation and thawed at different glycerol concentrated extender, it showed 52.7% motility and 57.7±10.3% viability at 7% glycerol, compared to other treatments. For semen cryogeny, at conditions of 5, 7cm and a height of 10cm for pre-cryogeny and maintaining the semen at 7cm from the surface of liquid nitrogen resulted in profitable motility and viability.

A total of 5 animals including 3 raccoons, 1 badger, and 1 fennec fox kept in outdoor exhibits at the Everland Zoological Gardens showed depression, anorexia, dyspnea, serous oculonasal discharge, diarrhea, and convulsions. All the affected animals died within 10 days after the onset of clinical signs. This outbreak lasted about 4 months. On necropsy, major gross lesions were confined to the lungs. Red to grey sublobular to lobular consolidations with various sized tan to reddish spots were observed in the lungs. Histopathologically, the pulmonary lesions were characterized by acute to subacute bronchointerstitial pneumonia with secondary bacterial or adenoviral infections. Intracytoplasmic eosinophilic inclusion bodies compatible with canine distemper virus (CDV) were found in the lung, urinary bladder, kidney, intrahepatic bile duct, stomach, small and large intestines. Multifocal areas of severe demyelination and accumulation of gitter cells or nonsuppurative inflammation were seen in the brains of 2 raccoons. CDV -specific antigens were demonstrated in the lung sections on immunofluorescent assay. The present report describes an outbreak of CDV infection in a zoo and indicates the range of susceptible zoo animal species.

A 2-year-old female lop-eared rabbit (Oryctolagus cuniculus) was presented to the veterinary clinic at a zoo with pruritus, alopecia, and crusting of the ear. Examination of skin scrapes revealed an infestation with the rabbit ear mite, Psoroptes cuniculi. Weekly subcutaneous ivermectin injection over a three-week period resulted in remission of the clinical signs and improvement of the overall conditions of the rabbit.
